There is no link that says CO2 causes warmer temperatures. When Al Gore got on his forklift and showed us that graph he didnt tell us that the temps and CO2 emissions were seperated by 800 years. The temp went up, then about 800 years later on ave CO2 went up. Which tells us something, but not what Gore thinks, or says.
The fact the earth is warming is not the debate. It is warming, it happens. Maybe because of us but not because of CO2 emissions. And if you think it is I would look up how much of the worlds greenhouse gases are produced by the beef industry THEN tell us electric cars are the answer.
